  • Title: Communicating with Light: from Telephony to Cell Phones Revision
    Title: Communicating with Light: From Telephony to Cell Phones Revision: February 1, 2006 Authors: Jim Overhiser, Luat Vuong Appropriate Physics, Grades 9-12 Level: Abstract: This series of six station activities introduces the physics of transmitting "voice" information using electromagnetic signals or light. Students explore how light can be modulated to encode voice information using a simple version of Bell's original photophone. They observe the decrease of the intensity of open-air signals by increasing the distance between source and receiver, and learn the advantage of using materials with different indices of refraction to manipulate and guide light signals. Finally, students are introduced to the concept of bandwidth by using two different wavelengths of light to send two signals at the same time. Special Kit available on loan from CIPT lending library. Equipment: Time Required: Two 80-minute periods NY Standards 4.1b Energy may be converted among mechanical, electromagnetic, Met: nuclear, and thermal forms 4.1j Energy may be stored in electric or magnetic fields. This energy may be transferred through conductors or space and may be converted to other forms of energy. 4.3b Waves carry energy and information without transferring mass. This energy may be carried by pulses or periodic waves. 4.3i When a wave moves from one medium into another, the waves may refract due a change in speed. The angle of refraction depends on the angle of incidence and the property of the medium. 4.3h When a wave strikes a boundary between two media, reflection, transmission, and absorption occur. A transmitted wave may be refracted.

It is therefore important to make it cheap and affordable. To be reliable and affordable over the common Public Switched Telephone Network, change is therefore inevitable to keep abreast with the global technological change. It is on this basis that this paper tends to critically review this new technology VoIP, x-raying the different types. It further more discusses in detail the VoIP system, VoIP protocols, and a comparison of different VoIP protocols. The compression algorithm used to save network bandwidth in VoIP, advantages of VoIP and problems associated with VoIP implementation were also critically examined. It equally discussed the trend in VoIP security and Quality of Service challenges. It concludes by reiterating the need for a cheap, reliable and affordable means of communication that would not only maximize cost but keep abreast with the global technological change. Keywords: Voice over Internet Protocol (VoIP), Public Switched Telephone Network (PSTN), Session Initiation Protocol (SIP), multipoint control unit 1. Introduction Voice over Internet Protocol (VoIP) is a technology that makes it possible for users to make telephone calls over the internet or intranet networks.

Subramanian 1Department of ECE, Sri Krishna College of Engineering and Technology, Coimbatore, India 2Department of CSE, Coimbatore Institute of Engineering and Technology, Coimbatore, India Received 2013-06-03, Revised 2013-07-17; Accepted 2013-11-21 ABSTRACT Speech enhancement has become an essential issue within the field of speech and signal processing, because of the necessity to enhance the performance of voice communication systems in noisy environment. There has been a number of research works being carried out in speech processing but still there is always room for improvement. The main aim is to enhance the apparent quality of the speech and to improve the intelligibility. Signal representation and enhancement in cosine transformation is observed to provide significant results. Discrete Cosine Transformation has been widely used for speech enhancement. In this research work, instead of DCT, Advanced DCT (ADCT) which simultaneous offers energy compaction along with critical sampling and flexible window switching. In order to deal with the issue of frame to frame deviations of the Cosine Transformations, ADCT is integrated with Pitch Synchronous Analysis (PSA). Moreover, in order to improve the noise minimization performance of the system, Improved Iterative Wiener Filtering approach called Constrained Iterative Wiener Filtering (CIWF) is used in this approach. Thus, a novel ADCT based speech enhancement using improved iterative filtering algorithm integrated with PSA is used in this approach.

  • Telecom Policy Forum: a Chance to Push Ip Telephony, Data Services
    P A U L, W E I S S, R I F K I N D, W H A R T O N & G A R R I S O N TELECOM POLICY FORUM: A CHANCE TO PUSH IP TELEPHONY, DATA SERVICES LAURA B. SHERMAN PUBLISHED IN TELECOMMUNICATIONS REPORTS INTERNATIONAL JANUARY 2001 PAUL, WEISS, RIFKIND, WHARTON & GARRISON The upcoming World Telecommunication Policy Forum (WTPF-01) will present an opportunity for all companies in the Internet value chain—equipment manufacturers, content providers, and network and service suppliers—to head off unneeded and unwanted regulation of the Internet. The International Telecommunication Union (ITU) is hosting the forum in early March for executives and regulators from the developed countries to explain the positive aspects of IP (Internet protocol) telephony and data services to their counterparts from the developed world. WTPF-01 is the third in a series of ITU forums on emerging policy and regulatory matters arising from the changing telecom environment. These forums do not result in legally binding obligations or commitments. Rather, they build understanding and set a direction for governments and regulators. The first policy forum, on global mobile satellite services, led to the establishment of an ITU registry and marking process for global mobile satellite terminals. A memorandum of understanding designed to facilitate the mutual recognition and cross- border transport of terminals also emerged. The second forum dealt with trade in telecom services. Participants reviewed the World Trade Organization’s negotiations on basic telecommunications services and the marketplace changes that resulted from the agreement. The ITU Council last year set the agenda for the upcoming forum’s discussion of IP telephony.

  • Low-Complexity Pruned 8-Point DCT Approximations for Image Encoding
    Low-complexity Pruned 8-point DCT Approximations for Image Encoding † ‡ V´ıtor A. Coutinho ∗ Renato J. Cintra F´abio M. Bayer Sunera Kulasekera Arjuna Madanayake.§ Abstract Two multiplierless pruned 8-point discrete cosine transform (DCT) approximation are presented. Both trans- forms present lower arithmetic complexity than state-of-the-art methods. The performance of such new methods was assessed in the image compression context. A JPEG-like simulation was performed, demonstrating the adequate- ness and competitiveness of the introduced methods. Digital VLSI implementation in CMOS technology was also considered. Both presented methods were realized in Berkeley Emulation Engine (BEE3). Keywords Approximate discrete cosine transform, pruning, pruned DCT, HEVC 1 INTRODUCTION Orthogonal transforms are useful tools in many scientific applications [1]. In particular, the discrete cosine transform (DCT) [2] plays an important role in digital signal processing. Due to the energy compaction property, which are close related to the Karuhnen-Lo`eve transform (KLT) [3], the DCT is often used in data compression [4]. In fact, the DCT is adopted in many image and video compression standards, such as JPEG [5], MPEG [6–8], H.261 [9,10], H.263 [7,11], H.264/AVC [12,13], and the high efficiency video coding (HEVC) [14,15]. Due to its range of applications, efforts have been made over decades to develop fast algorithms to compute the DCT efficiently [4]. The theoretical multiplicative complexity minimum for the N-point DCT was derived by Winograd in [16]. For the 8-point DCT, such minimum consists of 11 multiplications, which is achieved by Loeffler DCT algorithm [17].
